  • Transformed the medical forecast beyond its essential function as a financial reporting tool by adding member-segmented granularity that pinpoints emerging trends for targeted business actions. Present insights to Centene’s CFO in monthly calls.
  • Lead a team of six actuaries and data analysts providing regular guidance and skill training sessions in R.
  • Demonstrated ability to build strong collaborations with various technical and non-technical business partners with analytic support and business knowledge across medical, pharmacy, provider, membership, health status, sales, and payment data.
  • Proven record of flexibly adapting team workflow to incorporate forecast estimates for direct and indirect COVID costs and various health care policy changes that impacted membership makeup and anticipated costs.
  • Developed a member-level gross margin database that combines revenue (e.g premiums, risk transfers) and expense components (e.g. claims) from disparate EDW and financial sources with 40 targetable member, provider, and broker characteristics. Deployed drill-down shiny dashboard in RSConnect that is employed widely across departments to identify opportunities for business initiatives.
  • Identified an $8M annual initiative improving on risk adjustment code capture by data-mining pharmacy prior authorization data.
